Distributed Mobile-to-SuperCollider Music System

Overview

Four-node distributed music instrument:

• Mobile Phone: Touch/motion/gesture performance interface
• Vlingo: Voice-to-note mapping and vocal expression engine
• VPS Server: Orchestration, logic, routing
• Laptop: SuperCollider audio synthesis

System Architecture

Phone UI → Vlingo → WebSocket → VPS → OSC → SuperCollider → Audio Output Voice → Vlingo → WebSocket → VPS → OSC → SuperCollider → Audio Output

Context Grouping

The system is organized into four functional contexts using Domain-Driven Design principles:

Performance Context (Phone)

• Gesture capture and mapping
• 8x8 grid for note/drum triggering
• Motion controls for modulation
• Recording/loop controls

Orchestration Context (VPS)

• WebSocket server (Node.js/FastAPI)
• Event routing and normalization
• Musical logic engine (DDD bounded context):
• Quantization (beat grid alignment)
• Scale filtering (key restriction)
• Pattern generation (Euclidean rhythms)
• Variator (random injection)
• Session state management
• Timing coordination

Voice Context (Vlingo)

• Voice-to-note mapping engine
• Real-time vocal pitch tracking
• Syllable-based trigger system
• Harmony voice blending
• Vlingo acts as bridge between vocal expression and musical synthesis

Synthesis Context (Laptop)

• SuperCollider audio engine
• OSC listener for remote control
• DSP processing and FX chain
• Real-time rendering

Design Philosophy

Domain-Driven Design is coupled to context-aware coding and planning. Each context (Performance, Orchestration, Voice, Synthesis) represents a bounded context with clear responsibilities and communication boundaries. Video reference demonstrates DDD principles for distributed systems.

Current Focus

Building the real-time musical interaction pipeline with quantization and generative composition.
